DETAILED DESCRIPTION

[0016] The technical solutions of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The acid-adding equipment for lead-acid battery production involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] like Figure 1-5 As shown, in one embodiment, an acid-adding device for lead-acid battery production is proposed, including a machine base 1, a conveying assembly 2 and a support frame 101 are installed on the upper end of the machine base 1, a battery shell 3 is conveyed on the conveying assembly 2, a support plate 102 is installed at the front end of the support frame 101, an acid-adding assembly 4 is arranged in the support plate 102, the acid-adding assembly 4 includes a liquid injection mechanism 41 and a leak-proof mechanism 42, the liquid injection mechanism 41 includes a guide rod 411, a lifting seat 412, a positioning block 415 and a filling head 416, a plurality of guide rods 411 are all slidably connected in the support plate 102, the lifting seat 412 is slidably connected to the circumferential surface of the guide rod 411, a first spring 413 is fixedly connected between the guide rod 411 and the lifting seat 412, an output end of an electric push rod 414 installed on the upper end of the support plate 102 is fixedly connected to the lifting seat 412, a plurality of positioning blocks 415 are equidistantly installed on the surface of the lifting seat 412, and the filling heads 416 are all installed in the positioning blocks 415; The anti-leakage mechanism 42 includes a liquid discharge tube 421, a connecting ring 425, a sealing block 426 and a connecting rod 423. The liquid discharge tube 421 is slidably connected in the filling head 416. Multiple support blocks 422 installed on the circumferential surface of the liquid discharge tube 421 are all slidably connected to the filling head 416. The connecting rod 423 is installed at the lower end of the support block 422 and is slidably connected to the filling head 416. A second spring 424 is installed between the support block 422 and the filling head 416. The connecting ring 425 is installed in the filling head 416, and multiple sealing blocks 426 are installed in the connecting ring 425.

[0018] In actual application of the embodiment of the present invention, the conveying assembly 2 transports the battery shell 3 to the liquid filling position, and then controls the electric push rod 414 to operate, driving the lifting seat 412 to descend. At the same time, through the cooperation of the first spring 413 and the guide rod 411, the filling head 416 is pressed on the filling hole of the battery shell 3. At the same time, the connecting rod 423 is pushed upward and retracted into the filling head 416, thereby driving the support block 422 and the liquid discharge cylinder 421 to rise and separate from the blocking block 426, so that the lower end of the filling head 416 is opened. Then, lead-acid liquid can be transported into the filling head 416, so that the liquid passes through the connecting ring 425 and the blocking block 426 and enters the cavity of the battery shell 3, thereby achieving the effect of adding acid to the battery shell 3; After the liquid discharge tube 421 and the blocking block 426 overlap, the filling head 416 is completely avoided from dripping liquid.

[0019] like Figure 3-13 As shown, in one embodiment, a plurality of sets of rotating rods 427 are rotatably connected in the filling head 416, and a limiting plate 428 is installed on the circumferential surface of the rotating rod 427, and a third spring 429 is installed between the limiting plates 428. A limiting groove 4210 is provided on the surface of the support block 422, and a closing frame 4211 is slidably connected in the filling head 416, and an extrusion groove 4212 provided in the closing frame 4211 is slidably connected to the limiting plate 428, and a fourth spring 4213 is installed between the closing frame 4211 and the filling head 416.

[0020] When the embodiment of the present invention is actually used, when the filling head 416 is fitted with the filling hole of the battery shell 3, the closing frame 4211 is first retracted into the filling head 416, and then the connecting rod 423 is retracted into the filling head 416. When the connecting rod 423 is retracted into the filling head 416, the supporting block 422 and the liquid discharge cylinder 421 are synchronously driven to rise relative to the filling head 416. During the rising process, the extrusion groove 4212 provided on the surface of the supporting block 422 will slide with the limit plate 428, thereby pushing the rotating rod 427 to rotate, causing the limit plate 428 to shrink. When the connecting rod 423 is flush with the lower end of the filling head 416, the supporting block 422 will pass over the limit plate 428. Then, through the action of the third spring 429, the limit plate 428 is opened and reset to both sides. When the acid is added to the battery shell 3, the control lifting seat 412 and the filling head 416 are controlled. When the closure frame 4211 is lifted up and reset, the support block 422 is blocked by the opened limit plate 428 and will not fall relative to the filling head 416. At this time, the fourth spring 4213 pushes the closing frame 4211 to fall. When the extrusion groove 4212 provided in the closing frame 4211 contacts the limit plate 428, the limit plate 428 is squeezed and the limit plate 428 is collapsed and merged. At this time, the limit groove 4210 provided on the surface of the support block 422 passes through the limit plate 428. The second spring 424 pushes the support block 422 and the liquid discharge cylinder 421 to quickly fall and reset, thereby sealing the bottom of the filling head 416 and causing the bottom of the filling head 416 to vibrate, thereby shaking off the lead-acid liquid remaining at the lower end of the filling head 416 and preventing the subsequent liquid from dripping from the filling head 416.

[0021] like Figure 3 As shown, in one embodiment, a water pump 5 and a diverter cylinder 501 are installed on the upper end of the support plate 102. The water pump 5 and the diverter cylinder 501 are connected via a first connecting pipe 502. The output ends of the diverter cylinder 501 are connected to the filling head 416 via a first hose 503. The liquid extraction pipe 504 installed at the input end of the water pump 5 is connected to a storage tank for storing lead-acid liquid outside.

[0022] In actual application, the embodiment of the present invention controls the operation of the water pump 5, and then the liquid extraction pipe 504 extracts the lead-acid liquid in the external storage tank, and then transports it to multiple filling heads 416 through the first connecting pipe 502, the diversion cylinder 501 and the first hose 503, and finally replenishes it into the battery shell 3 through the filling head 416, thereby completing the battery acid addition operation.

[0023] like Figure 2 、 3As shown in Figure 5, in one embodiment, a negative pressure pump 6 and a shunt pipe 601 are installed at the upper end of the support plate 102. The negative pressure pump 6 and the shunt pipe 601 are connected by a second connecting pipe 602. The output ends of the shunt pipe 601 are connected to the filling head 416 through a second hose 603. A negative pressure pipe 604 is installed in the filling head 416. The second hose 603 is connected to the negative pressure pipe 604. The output end of the negative pressure pump 6 is connected to the input end of the purification box 606 installed at the upper end of the machine base 1 through an output pipe 605.

[0024] In actual application, when the battery is in the acid addition process, the negative pressure pump 6 is controlled to operate, and the negative pressure pump 6 extracts the gas from the cavity in the battery shell 3 through the second connecting pipe 602, the shunt pipe 601, the second hose 603 and the negative pressure pipe 604, so that a negative pressure environment is formed in the cavity of the battery shell 3. The air pressure difference is used to inject the acid into the battery more quickly, which significantly improves the acid addition efficiency. At the same time, the acid mist generated during the acid addition process can be extracted and transported to the purification box 606 through the output pipe 605 for filtration and treatment, thereby intercepting harmful substances in the acid mist and preventing them from spreading and polluting the surrounding environment.

[0025] like Figure 14-17 As shown, in one embodiment, a filter mechanism 7 is provided in the purification box 606, and the filter mechanism 7 includes a rotating column 701, a mounting disk 702 and a filter cartridge 703. The rotating column 701 is rotatably connected in the purification box 606, and the mounting disk 702 is installed on the circumferential surface of the rotating column 701. Multiple filter cartridges 703 are all installed in mounting holes opened on the surface of the mounting disk 702. A sealing seat 704 is slidably connected in the purification box 606, and a fifth spring 705 is installed between the sealing seat 704 and the purification box 606.

[0026] When the embodiment of the present invention is actually used, after the acid mist is transported into the purification box 606, the acid mist is filtered by the output end of the purification box 606 and the filter cartridge 703 at the corresponding position of the output end. After a long period of filtration, the filtering effect of the filter cartridge 703 will be reduced. By controlling the rotation of the rotating column 701, the rotating column 701 drives the mounting plate 702 to rotate, thereby achieving the effect of controlling the automatic switching of the filter cartridge 703. At the same time, the fifth spring 705 pushes the sealing seat 704 in real time, and the sealing seat 704 fits tightly with the filter cartridge 703, which can ensure the sealing effect of the filter cartridge 703 and prevent harmful gases from diffusing to the outside without filtration.

[0027] like Figure 14-19As shown, in one embodiment, a ratchet 8 is installed on the circumferential surface of the rotating column 701, and the rear end of the support frame 101 is rotatably connected to the rotating cylinder 802 through the rotating shaft 801. The circumferential surface of the rotating cylinder 802 is installed with a driving gear 803, a driving rod 804 and a limiting wheel 805. A guide frame 806 is installed between the machine base 1 and the support plate 102. A tooth plate 807 installed on the circumferential surface of the guide frame 806 is engaged with the driving gear 803. A sixth spring 808 is installed between the tooth plate 807 and the guide frame 806. A mounting frame 809 is installed on the upper end of the machine base 1, and a plurality of trigger blocks 8010 are equidistantly slidably connected in the mounting frame 809.

[0028] When the embodiment of the present invention is actually used, the trigger block 8010 limits the position of the lower end of the tooth plate 807. When the trigger block 8010 is controlled to move to the right and does not overlap with the lower end of the tooth plate 807, the sixth spring 808 will push the tooth plate 807 to move downward, driving the drive gear 803 to rotate. The drive gear 803 drives the rotating cylinder 802, the drive rod 804 and the limiting wheel 805 to rotate. Through the rotation cooperation of the drive rod 804 and the limiting wheel 805, the ratchet 8 will be driven to rotate at a specified angle, thereby achieving the effect of accurately controlling the switching of the filter cylinder 703.

[0029] like Figure 16-19 As shown, in one embodiment, the connecting plate 9 installed on the surface of the lifting seat 412 is slidably connected to the support frame 101, and a rack 901 is installed at the rear end of the connecting plate 9. The circumferential surface of the linkage shaft 902 rotatably connected to the rear end of the support plate 102 is installed with a one-way gear 903 and a first bevel gear 904. The one-way gear 903 is engaged with the rack 901, and a guide shaft 905 and a threaded rod 906 are installed in the mounting frame 809. The circumferential surface of the guide shaft 905 is slidably connected with a bevel block 907. The bevel block 907 is threadedly connected to the threaded rod 906 and is slidably connected to the trigger block 8010. The second bevel gear 908 installed on the upper end of the threaded rod 906 is engaged with the first bevel gear 904.

[0030] In actual application of the embodiment of the present invention, when the injection mechanism 41 is continuously in operation, the lifting seat 412 will continue to reciprocate and lift, thereby driving the connecting plate 9 to reciprocate up and down, and the connecting plate 9 drives the rack 901 to move synchronously, and the rack 901 drives the one-way gear 903 to rotate in one direction, and the one-way gear 903 drives the linkage shaft 902 to rotate in a single direction, and the linkage shaft 902 drives the first bevel gear 904 to rotate, and the first bevel gear 904 drives the threaded rod 906 to rotate through the second bevel gear 908, and the threaded rod 906 drives the inclined plane block 907 to rotate continuously. When the inclined surface block 907 contacts the trigger block 8010, the continuously descending inclined surface block 907 pushes the trigger block 8010 to the right via its inclined surface, causing the trigger block 8010 in the current position to release the restriction on the descending position of the tooth plate 807. At this time, the tooth plate 807 will immediately descend a certain distance, causing the rotating column 701 to intermittently rotate at a specified angle. When the injection mechanism 41 has filled the battery shell 3 with lead-acid liquid to a certain amount, the inclined surface block 907 will descend to a certain position and push the trigger block 8010 to slide within the mounting bracket 809. This achieves the effect of automatically replacing the filter cartridge 703 according to the operating frequency of the injection mechanism 41, reducing the frequency of manual replacement and ensuring the filtering effect of the acid mist.

[0031] like Figure 1 As shown, in one embodiment, the conveying assembly 2 includes a conveying frame 201, a connecting roller 202, a conveyor belt 203 and a positioning seat 204. The conveying frame 201 is installed at the upper end of the machine base 1, the connecting roller 202 is rotatably connected in the conveying frame 201, the conveyor belt 203 is connected between the connecting rollers 202, the positioning seat 204 is installed in the conveying frame 201, and the roller 205 rotatably connected in the positioning seat 204 is slidably connected to the battery shell 3.

[0032] In actual application of the embodiment of the present invention, after the battery shell 3 is located on the conveyor belt 203, the operation of the conveyor belt 203 will drive the battery shell 3 to move toward the acid adding component 4. During the movement, the front and rear positions of the battery shell 3 can be corrected by the roller 205 in the positioning seat 204 until the injection holes on the battery shell 3 all correspond to the position of the filling head 416. At this time, the conveyor belt 203 stops running, and then the acid adding operation of the battery shell 3 can be completed by the acid adding component 4.
